## anonymous one year ago I Will Medal And Fan! I need explanation AND answer! Evaluate the following. 12 divided 4 + 9 - 3 x 4

1. phi

have you learned order of operations?

2. anonymous

yes

3. idku

$$12\div 4+9-3\times 4$$ like this? (just wanna verify)

4. anonymous

yes

5. phi

you should remember divide first before add or subtract start on the left side and do 12 divided by 4 first. what do you get ?

6. anonymous

3

7. phi

yes, so replace $$12 \div 4$$ with 3 what do you have now?

8. anonymous

3 + 9 - 3 x 4

9. phi

ok, now look for any multiply (or divide) if you find one, do it.

10. anonymous

3 x 4 = 12

11. phi

ok, so replace 3*4 with 12 what do we have now?

12. anonymous

3 + 9 - 3 and idk what to do with the 12

13. phi

you had 3+9 - 3*4 you do the multiply

14. anonymous

i did. its 12

15. phi

yes, and how do write the new expression (it has to have a 12 in it)

16. anonymous

idk then

17. phi

3+9 - 3*4 replace 3*4 with 12 (they mean the same thing)

18. anonymous

3 + 9 - 12

19. phi

ok, now with just add subtract, work left to right first do 3+9

20. anonymous

21. phi

yes

22. anonymous

3 + 9 = 12, 12 - 12 = 0

23. anonymous

i've got a feeling this is somehow wrong but oh well

24. anonymous

its never been 0

25. phi

if this is the question $12\div 4+9-3\times 4$ then 0 is the answer

26. phi

in math, if you follow the rules carefully, you get the answer.

27. anonymous

Let's simplify step-by-step. 12 4 +9−3x(4) =3+9+−12x Combine Like Terms: =3+9+−12x =(−12x)+(3+9) =−12x+12 Answer: =−12x+12
